there are really no antibiotics (or other medications, for that matter) that I'd recommend for use in the display tank. You have to assess accurately what you're dealing with here. If it's just one eye that is inflamed- you're probably looking at an injury or other trauma to the eye, and you can remove the fish to a separate aquarium and administer Epsom salt to the water to help reduce the swelling (an old standby). If your fish has both eyes showing this condition, you will need to use medication, such as Maracyn, to treat the condition (always in a separate tank). Keep water quality as high as possible, and monitor the fish carefully.
